MACHINE FOR CALKING PIPE-JOINTS.

Specification of Letters Patent.

Application filed May 9, 1911.

Patented July 23,1912.

Serial No. 626,118.

To all whom it may concern:

Be it known that LGOLIN O. SIMrsoN,Jr., a citizen of the United States, residing at Flushing, in the city of New York and State of New York, have invented certain new and useful Improvements in Machines for Call:- ing Pipe-Joints; and I do hereby declare the following to be a full, clear, and exact description of the invent-ion, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to means adapted to be mounted upon sections of piping (for gas, water or other purposes) whereby the calking of the joints between successive sections may be rapidly and efiectively carried out. The device in question lends itself to operation either by hand or power, and in my more specific claims I have claimed the other parts of the machine in combination with a suitable motor.

I have illustrated one example of the various possible embodiments of my invention in the accompanying drawings, wherein Figure 1 is a longitudinal section of a portion of two contiguous pipe sections, showing my machine in place, and Fig. 2 is a transverse sectional view taken on the line 22 in Fig. 1.

At 10 is shown the enlarged end of a pipe section, into which there fits in the usual manner the opposite end of a similar section, shown at 11. The lead wool or other calking material is shown at 12, partly in place, the calking tool 13 being shown in contact therewith. This tool may have any convenient shape suitable to the particular job in hand. The calking tool 13 is firmly held in the holder 14, on the reciprocating member 15 of any well known form of high speed portable power hammer, indicated at 16. The details of construction of this element are well known in many forms, capable of operation'by electricity, compressed air or otherwise, and, as they form no part of this invention, they will require no description here.

At 17 is shown a foundation band adapted to be applied and firmly fixed to the end of the pipe 11. To facilitate applying and removing this band it is made in sections, as clearly shown in Fig. 1, which sections are joined by straps 1S suitably fastened to contiguous sections. In the preferred form shown, these straps are hinged, are riveted to the band 17 at one side of the hinge and fastened on the other side of the hinge by a threaded bolt 19. The foundation band 17 is firmly clamped to the pipe 11, preferably by means of bolts 20 threaded through the band at intervals and adapted to be screwed hard down upon the pipe 11. A vertical abutment 21 rises from the band 17 forming a projecting ring around the pipe, which may or may not be continuous. This abutment receives the direct thrust of the hammering tool 16. Surrounding the foundation band 17 is a traveling receiver adapted to hold the tool 16 and carry itaround the pipe 11 while the calking tool is in action. This receiver may be of any convenient form enabling it to receive and properly support the tool 16; but in the preferred form shown this element of my machine is adapted to receive the tool 16 at virtually any point in the entire circle. The foundation band 17 has an important function, as a carrier or support for the traveling receiver, since it affords a truly circular bearing upon which the receiver may travel. This insures a properly continuous bearing for all the wheels upon which the receiver is carried, which condition cannot be relied upon if these wheels have to run upon the usually untrue surface of the pipe itself. The bolts 20 afford a means whereby the foundation band may be easily and truly centered.

As shown in the drawings, the traveling receiver comprises an inner and an outer annular wall shown respectively at 22 and 23, and united by a radial ring-shaped wall 24 which forms the bottom of the tool-receiving recess. This wall is preferably provided with hardened pressure rollers 25,

adapted to make contact with the abutment 21, thereby lessening the friction against said wall as the receiver travels around the pipe 11. The traveling receiver is preferably provided with wheels or rollers 26, running upon the foundation band 17, and preferably upon suitable tracks 27 The walls 22 and 23 are preferably made in sections united in a manner similar to that described with respect to the band 17.

The elements so fardescribed comprise my invention in its broadest form, since it is obvious that the traveler carrying the tool 16 may be made to revolve by hand while said tool is in operation, thereby producing the necessary progressive hammering all around the joint to be calked. I prefer, however, to further improve this device, in a manner permitting the use of power for all the functions involved. For this purpose the outer wall 23 of the traveling receiver is provided wit-l1 suitable teeth 28 (only partly shown in Fig. 2) and these teeth are made to mesh with a pinion 29 driven by a suitable motor 30, mounted upon the band 17 or in any other suitable location. I do not limit myself to any particular form of motor in this connection, although an electric motor is suggested by my drawing. Neither am I to be limited to a direct connection of the pinion on the motor shaft as shown.

Various changes may be made in this device without departing from the scope of this invention and I am not to be limited to details, save as expressed in the respective claims following.

What I claim is- 1. A device of the class described comprising in combination a foundation band, means for securing the same upon a pipe, a traveling receiver adapted to move over said band and a power hammer on said re ceiver, substantially as described.
